ScanPower Support

Has anyone else had a problem with their item labels not being scanable in BoxT? My scanner works fine on book barcodes but on item labels it will not scan approx. 1 in 15 even if I reprint the label. I bought a new scanner, cleaned the Dymo LW 450 turbo, and i have contacted Scanpower about adjusting the format on the barcode to make them a little longer. I had a Brother printer that used the whole label for the barcode where as the Dymo is using only half the width of the label. I don't want to buy a new printer just to discover it's an application or browser issue. I'm wondering if this is causing some of my "mystery" stranded inventory.
